Statistics and Autism, There Are Things You May Not Know

Well welcome back loyal followers, today hits post 30 for Tumor 2 Autism. With over 500 visitors and 1300 views, we wanted to take a step back and actually discuss some statistic about autism. Not the most fun and enlightening story out there, but still information that is important to understand. So let’s get into it.


-About 1 in 59 children has been identified with autism spectrum


-ASD is reported to occur in all racial, ethnic, and socioeconomic groups


-ASD is about 4 times more common among boys than among girls


-About 1 in 6 children in the United States had a developmental disability in 2006-2008, ranging from mild disabilities such as speech and language impairments to serious developmental disabilities, such as intellectual disabilities, cerebral palsy, and autism


-Studies have shown that among identical twins, if one child has ASD, then the other will be affected about 36-95% of the time. In non-identical twins, if one child has ASD, then the other is affected about 0-31% of the time


-Parents who have a child with ASD have a 2%–18% chance of having a second child who is also affected


-ASD tends to occur more often in people who have certain genetic or chromosomal conditions. About 10% of children with autism are also identified as having Down syndrome, fragile X syndrome, tuberous sclerosis external icon, or other genetic and chromosomal disorders


-Almost half (44%) of children identified with ASD has average to above average intellectual ability


-Children born to older parents are at a higher risk for having ASD


-A small percentage of children who are born prematurely or with low birth weight are at greater risk for having ASD


-ASD commonly co-occurs with other developmental, psychiatric, neurological, chromosomal, and genetic diagnoses. The co-occurrence of one or more non-ASD developmental diagnoses is 83%


-Research has shown that a diagnosis of autism at age 2 can be reliable, valid, and stable.


-Even though ASD can be diagnosed as early as age 2 years, most children are not diagnosed with ASD until after age 4 years.


-Studies have shown that parents of children with ASD notice a developmental problem before their child’s first birthday


-The total costs per year for children with ASD in the United States were estimated to be between $11.5 billion – $60.9 billion (2011 US dollars)


-Children and adolescents with ASD had average medical expenditures that exceeded those without ASD by $4,110–$6,200 per year


-In 2005, the average annual medical costs for Medicaid-enrolled children with ASD were $10,709 per child, which was about six times higher than costs for children without ASD ($1,812)


-In addition to medical costs, intensive behavioral interventions for children with ASD cost $40,000 to $60,000 per child per year
